Vitalik Buterin:“隐身地址”概念以解决以太坊隐私保护难题
博链财经BroadChain获悉,近日, 以太坊 联合创始人Vitalik Buterin( V神 )发布文章《隐身地址的不完整指南》,指出以太坊生态系统后续的最大挑战之一就是隐私,并提出“隐身地址”(stealth address)概念作为可能的隐私解决方案。
“隐身地址”(stealth address)概念将会使P2P交易、NFT转移和ENS注册实现匿名化,从而起到用户保护作用。
Vitalik Buterin提出接收资产的用户可以生成并保存一个“支出密钥”,用于生成一个可以在ENS上注册的隐身元地址。
隐身元地址可以传递给交易发送者,发送者对元地址执行加密计算以生成一个属于接收者的隐身地址。
发送方可以将资产转移到接收方的隐身地址,还可以发布临时密钥以确认隐身地址属于接收方,每个新交易都会生成一个新的隐身地址。
Vitalik指出,除了实施“密钥盲化机制”之外,还需要采用Diffie-Hellman密钥协议算法,以确保隐身地址和用户元地址之间的链接不会公开,并利用ZK-SNARKs技术转移资金支付Gas费。
